This research note examined contemporary issues for meta-analysis with an example from the communication disorders literature. A significant proportion of experimental and quasi-experimental research results are not published in the mainstream literature, which suggests that publication bias is a potential problem for synthesis studies. Nonetheless, 50% of synthesis studies (meta-analyses) in communication disorders do not include statistical or visual procedures, e.g., fail-safe Ns or funnel plots, to reinforce the integrity of results. Tests for publication bias are recommended as routine procedures for meta-analyses.

Objective: Dental occlusion and the alignment of the dentition play crucial roles in producing speech sounds. The Arabic language is specifically complex, with many varieties and geographically dependent dialects. This study investigated the relationship between malocclusion and speech abnormalities in the form of misarticulations of Arabic sounds.

Speechreading-gathering speech information from talkers' faces-supports speech perception when speech acoustics are degraded. Benefitting from speechreading, however, requires listeners to visually fixate talkers during face-to-face interactions. The purpose of this study is to test the hypothesis that preschool-aged children allocate their eye gaze to a talker when speech acoustics are degraded.

Background: In patients with inflammatory bowel diseases (IBD), functional complaints frequently persist after the clearing of inflammation and are clinically difficult to distinguish from symptoms of inflammation. In recent years, the influence of bidirectional communication between the gut and brain on gut physiology, emotions, and behavior has been demonstrated.
Research Questions: What mechanisms underlie the development of functional gastrointestinal complaints in patients with irritable bowel syndrome (IBS) and IBD? What therapeutic approaches arise from this?

Neurological disorders significantly impact the central nervous system, contributing to a growing public health crisis globally. The spectrum of these disorders includes neurodevelopmental and neurodegenerative diseases. This manuscript reviews the crucial roles of cellular signalling pathways in the pathophysiology of these conditions, focusing primarily on glutaminase/glutamate/NMDA receptor signalling, alongside the mitogen-activated protein kinase (MAPK) pathways-ERK1/2, C-JNK, and P38 MAPK.
